They stopped forming long ago, and have been worn down over millions of years by the erosive power of water and wind. First is isostasy: the bigger a mountain gets, the more it weighs down its tectonic plate, so it sinks lower. Estimating that volume, geologists believe that the lowly Appalachians were once as high as the rugged Himalayas, and some now-vanished mountain in modern-day New Hampshire or North Carolina could easily have been taller than Everest is today. Geologists, it turns out, don't readily agree what height makes a mountain a mountain, but an elevation of 300 meters (1,000 feet) is generally high enough to earn the classification. Fact 2: Mount Everest is referred to as 'Sagarmatha' by Nepalese people. How many anions are there in 20.0 g of FeClX3\ce{FeCl3}FeClX3?
